Regardless of whether Microsoft Accounts will have 2-factor authentication, it seems there's already good news for people with Windows Phone 7.5/8 and a GMail account (or other account compatible with Google's authentication). Microsoft have released a new Authenticator app:
I've not tried it myself, but if you have Windows Phone and wanted to added extra security to a GMail account without needing to receive an SMS message to log in, there now seems to be another option.There's a strong indicator that there's truth to the report: the availability of an Authenticator app from Microsoft for Windows Phone 7.5 and 8, published last Friday with a version 22.214.171.124 release.
One commenter said the app "also works with Google's 2-step authentication," an indication that there could be a two-way street between Google and Microsoft systems. That could be very handy since Google offers its Authenticator app for Android, iOS, and BlackBerry and many people who might want to use Microsoft services will have those types of phones.
